Description
Technical field
The present invention relates to new structure fields, and in particular to the connection method and construction work of the vertical piece of assembled wall
Skill.
Background technique
The Office of the State Council on January 1 in 2014 sends out (2013) No. 1 files " green building action scheme " and proposes " to promote and be suitble to industrialization
The building systems such as prefabricated and assembly concrete, the steel construction of production, accelerate the prefabricated and mounting technology of architectural engineering, raising is built
Build industrialization technology integrated horizontal ".The assembled overlapped shear wall structural system introduced from Germany has the advantage that construction speed
Fast, the live sandstone amount of degree is small, construction quality is higher, (prefabricated double plates can replace traditional mould in work progress for template consumption reduction
Plate), preferable social benefit is generated, is gradually promoted the use of at home in recent years.Compared to assembling frame structure, there are more
The vertical splicing seams of vertical abutment joint, wall play an important role to Shear transfer of the structure under geological process, stress performance
Directly determine the overall performance of structure.
Shear wall linear type connecting node form type is more, and cast-in-place band connection is prefabricated overlapping wall more commonly used at present
Between vertical abutment joint mode, be generally cross-linked using stirrup and reserved U-shaped reinforcing bar in engineering or with reserved bar with hooked end
Connection, but the vertical splicing seams rigidity of two precast wall bodies is relatively weak compared with the cast-in-situ wall of the same strength of materials, not can guarantee component
Continuity and structure overall stability.
The utility model of Patent No. 201410523999.8 discloses a kind of line-styled basement shear wall and vertically spells
Stitch node and its construction method.Including the overlaid plate type shearing being made of two two interconnected prefabricated composite plate shear walls
Wall is connected between two prefabricated composite plate shear walls by prefabricated panel seam, at the node of connection, is disposed with double longitudinal direction
Joint bar, double longitudinal direction joint bar and stirrup binding connection form the structure of like configurations column, are microdilatancy water in prefabricated panel seam
Cement mortar.The invention can make shear wall be connected as the advantages that whole, control distress in concrete develops, but node edge joint position connects
Relay is relatively weak, and insulating layer need to also be arranged again on wall after wall installation.
Utility model content
Technical problem to be solved in the utility model, which is intended to provide one kind, can be such that self-heat conserving overlapped shear wall effectively connects
For the strong vertical connecting node of line-styled self-heat conserving overlapped shear wall of entirety, seam crossing good integrity, shock resistance and its apply
Work technique.
In order to solve the above technical problems, the technical solution that the present invention specifically provides: a kind of line-styled self-heat conserving overlapping is cut
The vertical piece node of power wall, including prefabricated panel, steel truss, " H " fashioned iron, closed stirrup, vertical muscle, pre-buried U-shaped muscle, self-compaction are mixed
Solidifying soil in-situ layer, insulation board.Insulation board is arranged on the inside of prefabricated panel, and steel truss connection two panels prefabricated panel simultaneously forms cavity,
H profile steel to be placed at cavity node and peg is welded at shape steel web, reserved horizontal reinforcement is bent at node by " u "-shaped,
And interlock with the welded closure stirrup placed at node and overlap the globality of enhancing overlapped shear wall, it is cast-in-place from vibrating in cavity
Self-compacting concrete.
The fashioned iron of seam joint cores setting can be i shaped steel, H profile steel and square steel tube.
Overlapped shear wall is made of insulating layer, two panels prefabricated panel and self-compacting concrete in-situ layer, insulation board with
4@of Ф, 100 × 100 anticracking steel fabric sheet is set between precast wall body.
Joint cores use full welded closure stirrup.
The utility model overcomes between existing assembled overlapped shear wall that vertical piece core space rigidity is low, connects between two panels wall
Connect the weak disadvantage of intensity.The beneficial effect is that welding is arranged by the joint cores for overlapping wall "-" type seam in self-heat conserving
There is the H profile steel of peg, and is interlocked using reserved U-shaped horizontal bar and welded closure stirrup and overlap the entirety of enhancing piece node
Property, when bearing the effect of the power such as vibration, earthquake, explosion, type steel skeleton is compared with the horizontal circumferential reinforcement of setting, due to fashioned iron
Ductility preferably and to node region restriction ability enhance, limit the development of distress in concrete, anti-reflective enhances to weight bearing power, knot
Structure has obvious omen before destruction, so that destructive process slows down, has given full play to the bearing capacity ability of concrete, connection
The anti-seismic performance of integral self-heat conserving overlapping wall is improved, and simplifies construction technology, guarantees construction quality, while pre-
Wallboard processed can be used as the template of in-situ layer, reduce the dosage and concrete wet construction of template, and overlapping wall carries insulation board,
Subsequent operation is reduced, material property is made full use of.
